Preheat oven to 350. In a large cast iron pan over medium heat, add 1 tablespoon coconut oil and spinach leaves. Cook 5 minutes, just until wilted, and place in a colander. Return pan to heat and add chiffonade collard greens. Cook 5 – 7 minutes, until wilted, and place in colander with spinach. Allow to cool 10 – 15 minutes until cool enough to handle and then squeeze out all moisture.
Meanwhile, in a large bowl, add all crust ingredients except remaining 1/2 of the water and mix with hands. Be sure to thoroughly mix crust before adding any more water and only add if crust is crumbly and will not form a ball.
Divide crust in half and press one half into a greased 9 X 13 glass baking dish. Place the other between two pieces of parchment paper and roll out to very thin with a rolling pin. Place baking dish with crust in it inside the oven and par bake for 10 minutes. Remove and set aside to cool.
Meanwhile, in cast iron pan, add 1 tablespoon coconut oil over medium heat. Add chopped onion and sauté 3 – 5 minutes. Add minced garlic scapes and cook 1 more minute until very fragrant. Add shredded chicken, a dash of apple cider vinegar, shiitake mushrooms and coconut milk. Lower heat and simmer about 5 minutes.
Stir in lemon zest, lemon juice, salt, fresh herbs, and parsley until everything is well incorporated. Pour over par baked crust and top with rolled out crust. Cut any edges or press down into pan to create a nice pocket and place dish in oven. Bake for 30 – 40 minutes or until the crust on the top is golden and firm. Allow to cool 5 minutes before serving.
